Dennis wages an all-out commando strike on the neighbourhood bully. But he inadvertently ""captures"" a toothache-ridden Mr.Wilson instead, and the two are stuck together on a wild odyssey to the dentist's office, filled with ""pains, trains and automobiles"". During their trek, Dennis learns a valuble lesson about the true nature of bullies...and manages to sneak in a little impromptu dentistry of his own!
